Description

Technical Field

[0001] The invention relates to the technical field of steel structures, and in particular to a steel structure supporting structure. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Therefore, steel structures are widely used in building structures abroad. In recent years, the application of steel structures in multi-story civil buildings in China has become more and more extensive. The steel columns of steel structure houses are node steel columns that connect steel beams in all directions. Since some steel beams are long, if some parts of the steel beams in the middle lack support, they are prone to collapse when vibrations occur. Therefore, support columns are generally used in the middle of the steel beams for support. Because they do not connect steel beams but only provide support, the existing technology generally has low requirements for the earthquake resistance of support columns.

[0003] With the development of modern industrial technology, houses can be built in batches and sets like machine production. The structural components produced by this manufacturing method are called prefabricated building components, and prefabricated steel structure columns are one of them. The existing prefabricated steel structure columns have the following problems in the actual installation process:

[0004] (1) After the bottom of the column is installed on the ground, the column and the concrete foundation on the ground are usually connected by screws. The screw connection is prone to rust, and metal parts such as screws need to be regularly treated for rust prevention. The actual maintenance of steel structure buildings is relatively difficult;

[0005] (2) A crossbeam is provided at the upper end of the column, and the crossbeam is rigidly connected to the column. When the foundation sinks or there is a disaster such as an earthquake, the column and the concrete foundation may deflect or tear, and the connection position between the column and the crossbeam may also be easily offset, causing the column to have a significant impact on the supporting stability of the entire prefabricated building.

[0034] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described in conjunction with the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors;

[0035] The following is combined with Figures 1 to 11 , the steel structure support structure of the present invention is described in detail:

[0036] In the existing assembled steel structure houses, especially small high-rise or high-rise houses, when the columns are actually constructed, the columns are in the shape of a round tube as a whole, and a mounting cap is set at the lower end of the column. The mounting cap is provided with a perforation in the circumferential direction. During the actual construction, the column is hoisted to the top of the base by a hoisting device, and the embedded bolts are passed through the perforations on the mounting cap. The fastening bolts are set to achieve a fixed connection between the column and the base. During the above construction, it is difficult to hoist and install the embedded screws and the columns, and repeated correction is required, which is inconvenient to install. In addition, since the columns support the entire steel structure, the columns are subjected to the load of the steel beams. While giving the column vertical stress, there is also horizontal stress. When the horizontal stress on the column is uneven, it is easy to cause wear on the connection between the column and the base. With the increase of service life, the embedded screws between the column and the base are bent and deformed, which leads to the risk of connection stability between the column and the base. The connection between the upper end of the column and the steel beam is welded or bolted. Therefore, when the foundation settles or other natural disasters occur, stress concentration occurs at the joint of the beam and tearing occurs, resulting in failure of the connection between the column and the beam.

[0037] To this end, the present invention proposes a steel structure support structure, comprising:

[0038] The support base 100 is disposed in the pre-buried concrete foundation 500 , and the support base 100 is combined with the receiving groove on the pre-buried concrete foundation 500 .

[0039] The support sleeve 200 is plugged into and matched with the support base 100 in a vertical direction.

[0040] The column 300 is disposed in the support sleeve 200 , and the support sleeve 200 supports the outer surface of the column 300 .

[0041] The connecting body 400 is disposed at the upper end of the column 300 , and one end of the crossbeam 700 forms a horizontal sliding fit with the connecting body 400 .

[0042] The driving mechanism drives the support sleeve 200 to move vertically along the column 300 and the linkage connecting body 400 is fixedly coupled with the upper end of the column 300 .

[0043] In one embodiment, the contour of the receiving groove of the slow-setting soil pre-embedded foundation 500 can be a cylinder or a cuboid, which can effectively implement the limitation of the support base 100 to ensure that the slow-setting soil pre-embedded foundation 500 reliably supports the support base 100 and prevents the support base 100 from tilting.

[0044] In one embodiment, the support sleeve 200 and the column 300 are cylindrically tubular as a whole. After the support sleeve 200 and the support base 100 are combined into one, the support base 100 can provide reliable support for the support sleeve 200 to prevent the support sleeve 200 from tilting, and the support sleeve 200 is mounted outside the column 300 to provide reliable support for the column 300 in real time.

[0045] In one embodiment, the crossbeam 700 is installed on the connector 400, and one end of the crossbeam 700 forms a sliding fit with the connector 400 in the horizontal direction. When the driving mechanism drives the support sleeve 200 to move vertically and combine with the support base 100 as a whole, the connector 400 can be linked to the upper end of the column 300 for fixing, thereby ensuring a stable combination between the connector 400 and the column 300, facilitating the detachable connection between the crossbeam 700 and the upper end of the column 300, and sliding fit between the crossbeam 700 and the connector 400. When the foundation sinks or other natural disasters occur, the crossbeam 700 and the column 300 are movably connected, and the column 300 can also implement reliable support for the crossbeam 700 in the vertical direction. The column 300 can also be in a horizontally movable state on the crossbeam 700, thereby eliminating the concentrated stress between the crossbeam 700 and the column 300, and avoiding the problem of connection failure between the crossbeam 700 and the column 300.

[0046] In one embodiment, in order to ensure the clamping reliability of the support sleeve 200 on the column 300, to ensure reliable support for the column 300, and to avoid steel structure connection defects such as tilting of the column 300, a clamping unit is provided at the upper end of the support sleeve 200, and the clamping unit is used to drive the support sleeve 200 to clamp the outer surface of the column 300.

[0047] In one embodiment, in order to ensure that the support sleeve 200 and the support base 100 are integrated into one, a limiting unit is arranged between the support base 100 and the support sleeve 200, and the driving mechanism drives the support sleeve 200 to move vertically along the support base 100. When the support sleeve 200 moves vertically to the lowermost end, the driving mechanism drives the support sleeve 200 to rotate, and the limiting unit fixes the position of the support sleeve 200.

[0048] In one embodiment, after the column 300, the support base 100 and the support sleeve 200 are installed, the support sleeve 200 is driven by the driving mechanism to move vertically downward along the support sleeve 200, and the support sleeve 200 is also driven to rotate, and the support sleeve 200 is combined with the limiting unit between the support sleeve 200 and the support base 100. The limiting unit can position the support sleeve 200 in the lower position to ensure that the support sleeve 200 and the support base 100 are combined as a whole, thereby ensuring reliable support for the column 300.

[0049] In one embodiment, in order to ensure the support of the support sleeve 200, the support base 100 can be stably placed in the receiving groove on the embedded foundation 500 to ensure reliable support for the column 300. The support base 100 is a columnar structure as a whole, and the support base 100 is provided with a cylindrical tube cavity. The support sleeve 200 is inserted in the cylindrical tube cavity. The limiting unit includes a limiting protrusion 210 arranged on the outer wall of the support sleeve 200. The support base 100 is provided with a vertical slide 110 and a horizontal limiting slide 120. The lower end of the vertical slide 110 is connected to one end of the horizontal limiting slide 120. The vertical slide 110 and the horizontal limiting slide 120 are for the limiting protrusion 210 to pass through. The driving mechanism drives the support sleeve 200 to move and rotate vertically, and links the limiting protrusion 210 to move along the vertical slide 110 and rotate into the horizontal limiting slide 120.

[0050] In one embodiment, the vertical slide 110 allows the limiting protrusion 210 outside the support sleeve 200 to pass through and vertically descend to the lower end position of the vertical slide 110. After moving to the lower end position of the vertical slide 110, the support base 100 is rotated to allow the limiting protrusion 210 to rotate into the horizontal limiting slide 120, so that the limiting protrusion 120 abuts against the upper and lower surfaces of the horizontal slide 120, thereby enabling the support base 100 to lock the support sleeve 200, ensuring that the support base 100 and the support sleeve 200 are combined into a whole.

[0051] In one embodiment, the horizontal limiting slideway 120 is an arc-shaped opening opened in the circumferential direction of the support base 100, and the opening can limit the limiting protrusion 210 so that the support base 100 and the support sleeve 200 are combined into a whole.

[0052] In one embodiment, a plurality of groups of the limiting protrusions 210 are arranged along the circumferential direction of the outer wall of the support sleeve 200, and the limiting protrusions 210 are arranged at intervals along the length direction of the outer wall of the support sleeve 200. The position and length of the vertical slide 110 correspond to the position arrangement of the limiting protrusions 210, and the position and length of the horizontal limiting slide 120 correspond to the position and rotation angle arrangement of the limiting protrusions 210. The upper side surface of the horizontal limiting slide 120 is provided with a first limiting surface 121 and a second limiting surface 122, and the first limiting surface 121 and the second limiting surface 122 are arranged in the up and down directions, and there is an arc transition between the first limiting surface 121 and the second limiting surface 122, and the upper plate surface of the limiting protrusion 210 abuts against the first limiting surface 121 or the second limiting surface 122.

[0053] In one embodiment, four groups of limiting protrusions 210 are arranged at intervals along the circumferential direction of the support sleeve 200, and the four groups of limiting protrusions 210 are arranged at intervals along the length direction of the support sleeve 200. Therefore, when the limiting protrusions 210 rotate and rotate into the horizontal limiting slide 120, the limiting protrusions 210 rotate from the first limiting surface 121 to the second limiting surface 122, and the limiting protrusions 210 are made to fit with the second limiting surface 122, thereby enabling the support sleeve 200 and the support base 100 to be combined in real time. The limiting protrusions 210 are arranged along the height direction of the support sleeve 200, so that the support sleeve 200 can form multiple combined limiting positions with the support base 100 in the length direction, thereby ensuring the reliability of the support base 100 in limiting the support sleeve 200, thereby ensuring the reliability of the support base 100 in supporting the support sleeve 200 in the length direction.

[0054] In one embodiment, in order to implement the clamping of the upper end of the support sleeve 200 against the column 300 and ensure reliable support for the column 300, the outer wall of the support sleeve 200 is provided with a through opening in the tube length direction, and the through openings are arranged in a plurality of groups along the circumferential direction of the support sleeve 200. The through openings divide the support sleeve 200 into a plurality of groups of tube petal bodies, and the limiting protrusions 210 are respectively installed on their respective tube petal bodies.

[0055] The clamping unit includes a clamping support ring 220 arranged on the outer ring of the upper end of the support sleeve 200, a sliding rod 230 is arranged at the upper end of the tube valve body, the sliding rod 230 is horizontal and arranged along the radial direction of the support sleeve 200, the sliding rod 230 and the clamping support ring 220 form a sliding fit, and the extended end sleeve of the sliding rod 230 is provided with a clamping spring 231, and the two ends of the clamping spring 231 are respectively against the sliding rod 230 and the support sleeve 200, and the support sleeve 2 00 is horizontally extended from the upper end thereof with a clamping drive block 240, the outer surface of which is provided with a first vertical surface 241 and a second vertical surface 242, the first vertical surface 241 and the second vertical surface 242 are connected by an inclined surface 243, the driving mechanism comprises a driving cylinder 600 sleeved on the outside of the supporting base 100, the driving cylinder 600 is vertical and the inner wall of the driving cylinder 600 abuts against the first vertical surface 241 or the second vertical surface 242, and drives the tube petal body to move along the radial direction.

[0056] In one embodiment, four groups of through openings are arranged along the circumferential direction of the support sleeve 200, so that the support sleeve 200 is divided into four groups of tube petals. When the driving cylinder 600 is started to move vertically downward, the driving inclined surface of the inner wall of the driving cylinder 600 transitions from the first vertical surface 241 to the second vertical surface 242, so that the clamping driving block 240 slides along the sliding rod 230, so that the four groups of tube petals are approached along the radial direction, and the four groups of tube petals can clamp the column 300, thereby ensuring the reliability of the support sleeve 200 in supporting the column 300.

[0057] In one embodiment, in order to ensure that the driving cylinder 600 is integrated with the entire embedded foundation 500, the receiving groove of the concrete embedded foundation 500 is in a closed shape as a whole, and a receiving opening 510 is provided at the edge of the receiving groove.

[0058] In one embodiment, the driving cylinder 600 is sleeved on the column 300, and the upper end of the driving cylinder 600 is combined with the upper end of the support sleeve 200. The driving mechanism includes a group of hydraulic push rods. When all components are installed, the hydraulic push rods are started to make the driving cylinder 600 move downward along the column 300, and the support sleeve 200 is linked to move vertically until the support sleeve 200 drops to the lowest point. The lower end of the driving cylinder 600 is clamped with the flange 610 through the receiving opening 510, and the rotating motor of the driving mechanism is started to rotate the driving cylinder 600, thereby linking the support sleeve 200. 200 rotates, the support sleeve 200 rotates, the limiting protrusion 210 can be rotated from the first limiting surface 121 to the second limiting surface 122, and the snap-fit ​​flange 610 is rotated to the notch of the receiving groove of the concrete pre-embedded foundation 500, and the limiting of the snap-fit ​​flange 610 is realized to ensure that the driving cylinder 600 is integrated with the receiving groove of the concrete pre-embedded foundation 500, and ensure the overall support of the support sleeve 200 and the support base 100, so that the driving cylinder 600, the support base 100 and the support sleeve 200 form a whole with the concrete pre-embedded foundation 500.
